The voice coil motor is the simplest type of electric motor, consisting of only a magnetic housing and coil. Its simple, customizable design comes with many advantages, including a high power to mass ratio, high acceleration, low to no hysteresis and zero cogging. due to their small size, they used for smaller, precise applications such as focusing, oscillatory systems and mirror tilting.
The AVM Series is our standard voice coil motor. This permanent-magnet direct drive actuator operates without backlash and cogging.
- Direct drive, zero cogging, zero backlash voice coil motors
- Low coil mass with very fast response and bandwidth
- No contact between coil and core movement (no wear and tear)
- Smooth motion at low speeds with limitless resolution
Applications and Industries
Used for smaller, precise applications such as focusing, oscillatory systems and mirror tilting. Often used in semiconductor manufacturing and audio systems, the smallest voice coil motors are used as pumps in medical and biomedical equipment.
